摘要：

This paper presents a SEPIC PFC converter for driving multiple lighting LED lamps. With the aid of this converter, high power factor and high efficiency can be achieved by a simple single-stage circuit with low device stress features. A burst-mode dimming method is used to regulate the current and brightness of multiple LED lamps. A laboratory prototype is also built and tested. With the prototype, high power factor can remain under universal input voltage operation and individual lamp brightness control.
